Trigger subsystemIEEE-488 Referenceer. Note that the Source Bypass for Arm Layer 2 and the Trigger Layer also loops around theDelay.If programmed for another pass through the specified layer (count >1), the bypass loop will notbe in effect even though it will still be enabled. The bypass loop will be in effect if operationfirst goes back into the previous layer (or idle).Enabling the Source Bypass for Arm Layer 1 and Arm Layer 2 also enables their Output Triggers.When operation leaves Arm Layer 1 or Arm Layer 2, the appropriate output trigger pulsewill occur. If the Trigger Link (TLINk) control source is selected, the output trigger will beavailable on the programmed Trigger Link output line. For all other control source selections,the output trigger pulse will be available at the CHANNEL READY Output connector. The OutputTrigger in these two layers is disabled when the Source Bypass is disabled.The Output Trigger in the Trigger Layer is always enabled and occurs after the Device Action.With ACCeptor selected, the bypass is disabled. Operation will not proceed through the specifiedlayer until the appropriate event occurs.Programmingexample10 OUTPUT 707; “:trig:tcon:dir sour; dir?”20 ENTER 707; A$30 PRINT A$40 ENDLine 10Line 20Line 30Enables the Source Bypass for the Trigger Layer and then queries the state of theSource Bypass.Addresses the 7002 to talk.Displays the state of the Source Bypass (SOUR; enabled).:ASYNchronous:ILINe :ARM[:SEQuence[1]][:LAYer[1]]:TCONfigure:ASYNchronous:ILINe Select input trigger line; Arm Layer 1:ARM[:SEQuence[1]]:LAYer2:TCONfigure:ASYNchronous:ILINe Select input trigger line; Arm Layer 2:TRIGger[:SEQuence[1]]:TCONfigure:ASYNchronous:ILINe Select input trigger line; Trigger LayerParameters = 1 Line #1= 2 Line #2= 3 Line #3= 4 Line #4= 5 Line #5= 6 Line #6Short-formformats:arm:tcon:asyn:ilin :arm:lay2:tcon:asyn:ilin :trig:tcon:asyn:ilin 5-143
